What games are you playing and what speeds are you getting? Additionally, please post your settings as screenshots.
Your CPU is fine for some games, but it hasn't aged well in terms of Dolphin's performance. Though newer builds should be faster than the last stable builds, if you set your IR to 1x and disable Anti-Aliasing and you still get slowdowns, this is highly indicative of a CPU bottleneck.
